Tucson's upstart semi-professional choir AwenRising is calling its concert Sunday an introduction of sorts.

The choir has been around a few years - it grew from three founding members in 2008 to 17 singers, a pair of guitarists and a music director today - but it has largely flown beneath the radar.

Founding member Amy Palmer said it wants to change that, starting with Sunday's "Folk Music from Near and Far." The program includes classical, modern and a capella arrangements of folk music from Canada, the British Isles, America and the Hebrides isles.

The concert also will include a piece by 87-year-old Scottsdale composer Kent Newbury, who has published nearly 300 works. His latest was published in 2012, Palmer said.

Newbury's works fit into the overall mission of AwenRising, whose repertoire ranges from ancient folk songs to contemporary choral works. At one of their earliest concerts, the group did a mashup of contemporary Masses that won it thunderous applause.

The idea to interweave sections from several composers' Masses into one work was the brainchild of music director Richard Hintze, a recent University of Arizona doctoral graduate. Hintze sings with the choir and conducts from within, Palmer said.

"That's a really different approach for a choral ensemble here," she said. "We really do all sorts of music. We all have classical training backgrounds. Some of our members are instrumentalists. A lot have had years and years of vocal training.

"We want to sing music the way it is written traditionally," she added. "There's a lot of interpretation and arrangements that are out there. We want to sing it vocally correct with the right vocal production."

AwenRising performed five shows in 2012 including appearances at Tucson Meet Yourself in the fall and the Tucson Folk Festival earlier this month.
